ITUB · Itaú Unibanco Holding S.A.

This filing reflects an administrative update to Itaú Unibanco’s regulatory disclosure infrastructure, specifically the designated portal for publishing material facts under CVM Resolution No. 44/21. The change does not involve financial performance, governance events, strategic transactions, or operational developments; it solely concerns the digital channel used for compliance-driven transparency. While ensuring continued accessibility for shareholders and market participants, the update carries no direct financial, legal, or strategic implications for investors. The resubmission of the Registration Form and Disclosure Policy confirms procedural adherence but introduces no substantive revisions to disclosure practices, timing, or content standards. As such, the event is operationally routine and low in investor impact.
